Quercus and Pinus are similarly uncommon in the TR cores. Within TR 1
samples, Quercus pollen ranges from 0.0 4.5 percent of total pollen and spores,
and in TR 2 samples the range is 0.41 2.7 percent. Cohen (1975) determined a
range of average values of 4.2 10.3 percent for Quercus in seven Okefenokee
environments and found that the polten never occurred as less than 3.0 percent
of total pollen/spores. Pinus appears in TR 1 samples in amounts between 2.2 -
8.4 percent, while in TR 2 samples the range is 3.1 16.0 percent. Cohen (1975)
identified at least 6.0 percent Pinus in all his modern Okefenokee environments,
and identified average values of 12.4 36.0 percent.
 The low levels of Quercus and Pinus pollen in the TR samples indicate that
the trees did not grow near the sites of peat deposition. This is somewhat para-
doxical because the nearby sandy beach ridge should have been a very suitable
place for the trees to live. It is possible that the trees lived just far enough from
the swamp that their pollen failed to accumulate in large quantities and were
masked by the local, heavy production of shrub pollen.
 Aside from the gross compositional characteristics of the TR samples, there
are detailed vertical changes in palynomorph composition which reflect the plant
community successions at the sample sites. In the lower half of TR 1, an abun-
dance of Taxodium, Ilex, Myrica, and cf. Corylus, accompanied by
Myriophyllum (water-milfoil) and Graminae pollen suggests that cypress forest,
with shrubby undergrowth and clear, standing water occupied the site. At
16.33 m below the surface, Taxodium pollen declines noticeably, while pollen
and spores of herbaceous species become more abundant (Cyperaceae, Osmunda,
and eventually, Sphagnum and Woodwardia). Between 16.33 15.74 m
Gordonia and Cyrilla both occupied the site, accompanied by Ilex, Myrica and
cf. Corylus. The change from a bald cypress-dominated community to one
inhabited by shrubs and herbs could have been due to environmental changes
brought about by a period of drought and forest fires. J. Yeakel (personal
communication) reports that a layer of charcoal was found in core TR 1 at
16.5 m, just below the level of palynofloral transition.
 Plant succession at the TR 2 site was similar in some respects to that at
 TR 1, though there were differences in detail. For example, between 17.83 -
 18.66 m an herbaceous assemblage with abundant ferns and scattered shrubs
 dominated. This is shown by an abundance of Osmunda spores, with
 Cyperaceae, Sagittaria (arrowhead, or duck potatoe, and Graminae pollen,
 Woodwardia spores and Myrica, Ilex, and cf. Corylus pollen. Virtually all taxa,
 including Taxodium, decrease in abundance markedly at 17.83 m. Myrica and
 Cyrilla show obvious increases at that depth. This stratigraphic level is the same
 as that within the TR 1 core where Taxodium concentrations dropped. The
 fire and dry conditions which altered vegetation at the TR 1 site evidently had a
 similar affect on plants at TR 2. Following the disturbance, a shrub-dominated
 swamp developed and produced the sediment between 17.83 16.76 m. Note
 that, at both locations, Cyrilla rose to prominence toward the end of peat
 deposition.
